Annlication filed January 27, 1912. Serial No. 673,823.

To all whom it may concern:

Be it known thatl, J arms H. AMEsBURY,

"a citizen ofthe United States, residing at boards and tubes, such asare employed in packing'bot-tles and other frangible articles, theinvention also relating to improvements in packing boards and tubes ofthis class and consisting, in connection with a facing sheet of acorrugated sheet or strip provided with corrugations which are arrangeddiagonally with respect to and extend across the facing strip, oneobject of the invention being to provide an improved machine of thiskind which forms -a sheet or strip of paper with diagonal corrugations,another object of the invention being to provide an improved packingboard or tube with a sheet or strip Which is formed with diagonalcorrugations whereby the strength of the packing board or tube is verygreatly increased.

The invention consists in the construction, combination and arrangementof devices, hereinafter described and claimed.

In the accompanying drawingst-Figure 1 is a vertical longitudinalsectional view of a corrugating machine and tube forming machineconstructed in accordance with my invention. Fig. 2 is a plan of thesame. Fig. 3 is a vertical transverse sectional view of the same on theplane indicated by, the

' line 8-3 of Fig. 1. Fig. 4: is a detail per spective view of one formof packing board constructed in accordance with my invention withdiagonal corrugations. Fig. 5 is a similar view, showing another form ofmy improved packing board. Fig. 6 is a sectional perspective view,showing a packing tube constructed in accordance with my invention.

Referring particularly to the machine shown in Figs. 1, 2 and 3, inaccordance with my invention, I provide a pair of corrugating rolls 1which are arranged side by side and are mounted for revolution in asuitable supporting frame 2 which is provided with bearings 3. Theserolls are provided with corrugations 4 which are spiral, the pitch ofwhich is about 45 and which gations engage.

is run between them to be corrugated thereby. In connection witlrthepair of corrus. gatlng rolls, I provide feeding means such for instance,as a series of rollers 5 which are arranged to one side of thecorrugating rolls.- Atthe opposite side of the corrugated rolls is aspindle 6 which is arranged at an angle of about 45 with respect to therolls, is appropriately spaced therefrom and is provided with a suitablesupport 7. For

the'purposes of this specification, a crank handle 8 is shownconnectedto the axis of one of the rolls to enable the rolls to be ro.tated in the direction indicated by the arrows, so as to cause them toprovide a paper strip a fedbetweenthem, with bias or diagonal.corrugations Z). The paper strip or sheet fed to the rolls is initiallygathered to some extent by the feed rolls;

In the operation of the machine, the tension on the strip or sheet ofpaper running between the corrugating rolls is such on the far side ofthe corrugating rolls as to tend to wind the strip or sheet spirally soas to form a tube 0011 the spindle. This tube is backed on its outerside by a paper backing d, glued or otherwise united thereto. hendesired, I can also put an inner facing on the sheet. The tube thusformed is provided with longitudinal corrugations on its inner sidewhich extend therethrough from end to end and render the tubeexceedingly strong. .lVhere the spindle is not employed the paper, asit'issues in corrugated form from between the corrugating rolls passesbetween forming rolls or devices 8 which are employed to paste either asingle or double backing sheets on one or opposite sides of thecorrugated sheet.

For the purposes of this specification, I show a packing boardconstructed in accord ance with my invention, which comprises acorrugated sheet a and a single-backing sheet 0, the corrugations Ibeing diagonal, that .is to say, being substantially atf -an angle of 45with respect to the edgesofthe packing board. In Fig. 5, I how anotherform of packing board in accordance with my invention in which twobacking sheets indicated respectively at e and f. are employed, and
